SHLIB {utils}R Documentation

Build Shared Library for Dynamic Loading


Compile the given source files and then link all specified object files into a shared library which can be loaded into R using dyn.load or library.dynam.


R CMD SHLIB [options] [-o libname] files


files a list specifying the object files to be included in the shared library. You can also include the name of source files (for which the object files are automagically made from their sources) and library linking commands.
libname the full name of the shared library to be built, including the extension (typically ‘.so’ on Unix systems). If not given, the name of the library is taken from the first file.
options Further options to control the processing. Use R CMD SHLIB --help for a current list.


R CMD SHLIB is the mechanism used by INSTALL to compile source code in packages. Please consult section ‘Creating shared objects’ in the manual ‘Writing R Extensions’ for how to customize it (for example to add cpp flags and to add libraries to the link step) and for details of some of its quirks.

Items in files with extensions .c, .cpp, .cc, .C, .f, .f90, f95, .m, .M and .mm are regarded as source files, and those with extension .o as object files. All other items are passed to the linker.


Some binary distributions of R have SHLIB in a separate bundle, e.g. an R-devel RPM.
